VIMPROVEM'ENTIIN MACHINES FOR CRIMPING SEAMLESS FoXmes FOR BooTs AND SHOES,

Specification forming part of Letters Patent No. 199,714, dated January 29, 1878; application filed December 31, 1877.

To all whom it may concern:

Be it known that I, HENRY HiiBEL, of the city, county, and State of New York, have invented anew and Improved Machine for Crimping Seamless Foxing, of which the following is a specification:

- In the accompanying drawings, Figure 1 i represents a plan view, Fig. 2 a side elevationi partly in section, and Fig. 3 a sectional en elevation, of my improved machine for crimp-- catin g adjustable jaws, between which the foxing is taken hold of, to be stretched over the crimping-block.

Referring to the'drawin gs, A represents the supporting-frame of my improved crimpingmachine, and B the crimping-block, that is rigidly secured to one end of the frame, with the heel portion above the table of the frame and the toe portion extending downward.

The seamless foxing, which is cut as shown in Fig. 4, is placed on the crimping-block, and the tongue or stay of the same secured to front pins a of the block by a swinging lever-arm, O, with perforated upper jaw and roughened face. The lever-arm O is applied to or re moved from the block by a hand-lever, O,

and by a connecting eccentric or crank rod,

and serves to secure the foxing to the block against the longitudinal strain in crimping. The sides of the foxin g are taken hold of by sliding and stretching jaws D at both sides of the block B, which are applied by a treadle,

D, being fulcrumed to each other below the crimping, and the-inner set of jaws guided in in a lateral recess of the crimping-b1ock,while the ends of the outer jaws are opened or closed by cross-rods connected to the treadle,

and by spiral suspension springs. These stretching-jaws serve to retain the foxing at the sides of the crimping-block, so as to expose the quarters of the foxing to the crimping strain. This strain is produced by swinging and reciprocating crimpingjaws E E, which are guided by base rails along grooved and swinging arms E that are intermittently raised and lowered by suitable top and bottom cams, actuated by suitable gearing. The front jaw is connected, by pivoted side rods 01, to revolving crank-disks d, that impart reciprocating motion to the jaws-a backward motion when the guide-jaws are lowered into position at both sides of the crimping-block, and a forward motion when the guide-arms are raised above the crimping-block.

The crimping-jaws E E correspond to the shape of the crimping-block B, and .serve to clamp the quarters of the foxingbetween them, the jaws assuming aposition, one in front, the other back, of the foxing, the rear jaw being pressed toward the front jaws by hand or by suitable springs. The fiont jaw E is broader, and has adjustable side checks, that may be set by top screws 6 and wedge-pieces e to the thickness of the leather to be crimped, while the rear jaws E are beveled to a sharp front edge, so as to cause, by their joint backward motion, the quarter of the foxing to be drawn through between the jaws and crimped onto the block B. The foxing receives thereby the shape shown in Fig. 5, and may then be applied directly in the manufacture of shoes and gaiters. When the jaws arrive at the end of their receding motion, their guide-arms are raised so as to lift them above the crimping, block, and admit of the removal of the crimped foxing by releasing the side jaws and withdrawing the stay-retaining lever jaw. The next foxing is then placed in position and the same operation continued, the foxing being thus crimped at the quarters by a machine driven by any suitable power, and made ready for being worked up in aquicker and more economical manner than if crimped by hand.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentf 1. A machine for crimping seamless foxin g,

block, substantially as and for the purpose de-,

scribed.

2. The combination of the fixed crimpingblock, having front pins and sliding side jaws,

with a lever-acted tongue-holding jaw, fitting on the pins, and with treadle-actedswinging side jaws, that close on or open from the sliding jaws to secure or release the foxing, substantially as described, and for the purpose specified.

3. The combination of the fixed crimpingblock with the correspondingly-shaped front jaw, having adjustable cheeks, and with the sliding and guided rear jaw, having beveled edge, substantially as described, and for the purpose specified.
